Abstract

With the fast progression of digital data exchange in electronic way, information security is becoming more important in data storage and transmission. Cryptography has come up as a solution which plays a vital role in information security system against malicious attacks. The confidentiality, Integrity and Availability are the three main goals of Information Security. To protect Confidentiality and Integrity of the message, key mechanisms and Hash functions are used. This paper proposes a novel scheme, which computes Hybrid HMAC based on improved SHA-512 algorithm. The proposed system gives a constant output of 512 bits for any input length of data and generates HMAC using multiple available keys. Paper also provides a method for reducing the time taken by traditional HMAC functions and increases complexity of SHA-512.
